Surface Water Quality Criteria
(48)(b) In no case shall nutrient concentrations of a body of water be altered so as to cause an imbalance in natural populations of aquatic flora or fauna.
Numeric interpretations of the narrative nutrient criterion in paragraph 62-302.530(48)(b), F.A.C., shall be expressed as spatial averages and applied over a spatial area consistent with their derivation. In applying the water quality standards, the Department shall take into account the variability occurring in nature and shall recognize the statistical variability inherent in sampling and testing procedures.

Antidegradation Permitting Requirements; Outstanding Florida Waters; Outstanding National Resource Waters
Stated otherwise, if an upstream discharge ultimately flows into a downstream OFW (i.e., the discharge to the OFW is indirect), then the upstream discharge cannot significantly degrade the OFW. Because no proposed project is expected to constitute a direct discharge into an OFW or to significantly degrade an OFW, any additional OFW requirements are unlikely to apply.
